To all 107mm it may concern:

Be it known that I, Foanns'r B. MaoNan, citizen of the United States,residing at Dayton, county of Montgomery, and State of Ohio, haveinvented certain new and useful Improvements in Systems of ElectricalDistribution and Control, of which the following is a full, clear, andexact descrintion.

This invention relates to an improvement in systems of powerdistribution and control, and particularly to systems of this character,which are employed in conjunction with internal combustion or explosionengines. I

One of the primary objects of the present invention is to provide asystem of devices for imparting power to the engine to start or make thesame self-actuating and to receive power from said engine when the samebecomes self-actuatin to store up power to be used in future startingoperations, wherein a main operating member is capable of controllingthe associated instrumentalities of the system of d vices for efi'ectmgthe transmission of power to start the engine and the transmission ofpower from the engine to a storage source.

In systems similar to those which are described, claimed and illustratedin the copending applications of Charles F. Kettering, filed June 15,1911, Serial No. 633,443; filed September 19, 1912, Serial No. 721,237,there is provided a starting device or ma chine, normally disconnectedfrom the engine but having coupling mechanism so arranged that it may beshifted to connect the engine and starting device together. There isalso provided a means for imparting a slow initial movement to thestarting device or machine, to facilitate the coupling up of the engineand starting device, which, of course, must take place previous to orconcurrently with the shifting of the coupling mechanism. The systemsdescribed in the above mentioned co-pending applications also includecertain connections between the starting device and the source of powersupply, which must be shifted to permit the operation of the startingdevice for initially actuating the engine.

Another object of the present invention is to combine a starting deviceor system of the above mentioned type and an ignition system, for theprime mover or engine, with a main operating member, so that said memberwill be capable of effecting not only the functions incident to bringingthe starting system into operation to start the engine, but will alsoeifect the establishment of the ignition system or systems, eitherconcurrently with or in any desired timed relation, relative to thebringing of the starting system into operaticn to start the engine.

It is well known that certain types of ignition systems embodycharacteristics which make them peculiarly eflicient for use during thestarting operation of engines, while certain other types of ignitionsystems embody different characteristics which better adapt them forfurnishing ignition, after the engine has become selfactuating.

As an illustration of the above, it is well known that ignition of thevibrating spark type is peculiarly eilicient during the startingoperation of the engine, because of the quick succession of sparks whichoccur for each time that the circuit is closed. However, it is equallywell known that it is not advisable to employ the vibrating spark typeof ignition for ordinary running purposes, inasmuch as the currentconsumption in a system of this type is excessive and does not, as amatter of fact, give any greater etliciency than other types of ignitionsystems which are much more economical.

In the co-pending applications of Charles F. Kettering, filed September15,1909, Serial No. 517,788; filed March 12, 1910, Serial No. 548,921;and in the co-pending application 01" Charles F. Kettering and villi-amA. Chryst filed November 20, 1912. Serial No. 732,453; there isdescribed, claimed and illustrated systems wherein ignition of thevibrating spark type may be brought into use for certain purposes, whichare more efficiently met by ignition of this type, in combination withcertain types of what is known as single spark ignition and which is, ashas been described in the aforementioned co-pending applications, thepreferred type of ignition for ordinary running purposes.

ln the present invention, a plurality f diil'ercnt ignition systems areprovided, in combination with a starting system, which may be similar tothat disclosed in the copending applications of Charles F. Kettering,filed April 17, 1911, Serial No. 621,512: filed June 15, 1911, SerialNo. 633,i+l-3; ard filed September 19, 1912, Serial No. 721,237; whereina main operating member is pro vided for controlling the starting systemand which is also capable of establishing ignition systems of thevibrating and single spark type of ignition, concurr ntly with, orprevious to, the operation of the starting system, to start the en ine.However, in order to conserve the source of current vvhich supplies thevibrating spark system, the provisions which are operated by the mainoperating member, to bring said vibrating spr rl; system into operation,are only maintained in position to establish this ignition system duringthe period that the main operating member is maintained in position tocause the op ration of the star ing device. However, the provisionswhich are operated. by this main operating member for establishing thesingle spark type of ignition, are held in such position as to provideignition of this type, by certain cooperating elements which willmaintain this system in established condition for such time as isdesired, regardless 01" the movement of the main operating member, tocut out the starting operation of the starting device and to alsodis-establish the vibrating spark system.

A further object of the present invention is to provide certain of theelements for controlling the difierent systems of ignition, which may beoperated independently or concurrently with the main operating memher.

A still further object of the resent in vention resides in the provisionof a controlling element for starting systems for engines, incombination with a positive locking mechanism, which will maintain saidoperating member in inoperative position, said locking mechanism beinginoperative when the operating member is in other than its normalposition.

Further objects and ad *antagges Will be apparent from the followingdescription, reference being had to the accompanying drawings, wherein apreferred form of one embodiment of the present invention is clearlyshown.

In the co-pendine a k tpplications e F. Hotter-ins. lilec. June 15,1311, and iep :em r No. TQLQST, there is shov. ment for a startii c ablycomprise. the ens" \vhich, besides having it of controlling; th:

cend

. ain .t trcls the startinp' c. n explained in the tions, it is firstncces elemental element, s

ton switch, for closing a supplemental circuit which effects thecoupling up of the clutch pedal and the shiftable connections of thestarting device. This connection be tween the clutch pedal and theshiftable connections of the starting device, is accomplished by theoperation of what is termed, a clutch magnet. In order to simplify theconstruction as much as possible, this clutch magnet was placed inseries with the circuit which transmitted power to the starting device,to effect the slow initial movement thereof. In the present invention,as will be seen hereinafter, this starting clutch magnet has beenentirely dispensed with, well as the push button switch, while theclutch pedal is used only to perform its normal functions of controllingthe engine clutch.

Referring to the diagrammatic view of the drawings, the numeral 20designates a dynamo.-electric-machine, being shown in the presentinstance as comprising a generator 21, and a motor 22, preferably socombined that they form but a single unit. Cf course, from allintentions of the present invention, this dynamo-electric-machine mayeither be of that type shown and described int he copending applicationof Charles F. ,laettering, filed September 19, 1912, Serial No. 721. 37,or of the typeshown and described in the copending application ofCharles I. Kettering, filed June 15, 1911, Serial No. (533,443, or as amatter of fact, the dynamoelectric-machine may be entirely dispensed ithand a simple electric motor may lie employed in conjunction with astorage batterv, to give the starting power.

The motor shown in the present lnvention is of the series wound type,and when in operation through the shifting of the switch 25, has thefollowing c1rcu1t: from the storage battery 29, the current flowsthrough the wire 28, common switch rod 2?, brush 26, red 24-, throughwire 23, series winding 31, through the motor 22 and back to thebattery, via wires 32 and 30. However, it will be noted that normallythis circuit 18 broken by the position of the switch brush 26, which,when the electric machine is )I type shown in the co-pending applicationof Charles F. Kettering. filed September 19, 1912, Serial No. 721,237,normally closes the the generator circuit in the manner fully describedin said copending application.

\Vhen the electric machine is being employed as a generator to store uppower in the accumulator 29 for future starting operations, or tofurnish current for any desired work circuits, the sliding switch plate26 will be in the position shown in Fig. 1. In order to prevent theaccumulator 29 from charging back through the sliding switch element tothe generator armature and field windings, at such times as the voltageof the accumulator is greater than the voltage across the brushes of thegenerator, a cut-out relay device is included in the generator circuitand is of such construction that when the voltage of the generator fallsbelow that of the battery, the main circuit will immediately be openedand maintained in open condition until the voltage of the generatorrises above the voltage of the accumulator. This cut-out relay devicecomprises a fine winding 34 which is directly across the generatorcircuit, and is of such construction that as soon as the voltage of thegenerator has risen to a predetermined point, (preferably a little abovethe battery voltage), the contacts and 37 will be closed, thuspermitting current to flow through the main line or the generator to thebattery for charging purposes.

A. detailed description of the generator circuit will now be given. Assoon as the generator starts to build up, current will flow across thearmature 21, through brush 98, wires 10 and 11, fine wire coil 34: tothe opposite side of the line, by means of the wire Now, as soon as thevoltage builds up sufiiciently in the coil 34, the contacts 36 and 37will be closed, so that the current from the generator will flow throughthe coarse winding 35 of the relay, through contacts 37 and 36, directlyto the battery, via wires 13 and 30.

A description of the ignition systems em bodied in the presentinvention, will not be given in detail, in the present application,inasmuch as these systems were fully described and shown in connectionwith the eo-pending application of Charles F. Kettering and lVilliam A.Chryst, filed November 20, 1912, Serial NO. males.

In the present system, an ignition switch is embodied, wherein aplurality of controlling elements are so arranged that they may beoperated independently of each other, to establish ignition systems ofdifferent types independently, or they may be operated in certaincombinations to provide ignitions of different types concurrently.

The internal structure of the switch mechanism, that is, the arrangementof the contacts, detent and supportin elements, is substantially thesame as described in the bove mentioned co-pending application and willnot be referred to in detail herein, except wherein this structurerelates specifieally to the present invention. However, in the presentinvention, I have combined with an ignition system of the type set forthin the above mentioned co-pending application a main operating memberwhich may be actuated in any desirable manner, in the present instance,there being shown a plate to facilitate the operation thereof by foot,and a handle which may be used when it is de ired to operate the samemanually.

This operating member comprises either CID and is the rear covr of saidswi'ch. ring has a chain er l \x'iierei lG LGDt, preferably coil springoned, which normally ha the inter he chamber as one of its 1 abutmentwasher 46 which is pinned the rod lL, as

ment. The functioi of thi. spring is to assist in maintaining the rod inits outer most or inoperative position. '1 e rod if) is 1 provided witha reduced threaded ortion L6, shown in dotted lines, which is screwedinto an internally threaded bore, form d in one end of the rod e7. Byreferring to Fig. 8, this structure 'will be clearly understood. Betweenthe rods l2 and L7, there is secured an arm 4-9, (see Figs. 7 to 10).This arm has an enlarged portion 50, provided with an aperture 51, whichwill just lit orer the r duced threaded porti n oi the rod L2, but whichis of less diameter than the normal diameter of said rod, QT he oppositeends of this arm are bifurcated as at 52, one end be ing adapted toengage with ;he shank of the controlling element 5%, which, in thepresent instance, controls the single spark type of ignition, of eitherthe battery or magneto t pe, such as has been described in theco-pending application of Charles F. Kettering and l filliam Chryst,filed llOYQlDlJG-l 20, 1919, Serial No. YBQASZB. The opposite end ofsaid arm 49 engages with the controlling element 56, operable toestablish the vibrating spark type of i niiion.

It will be noted from an inspection of Fig. T, that switch shown thereinhas the controlling element for the vibrating spar: t me of ignition,positioned diametrically opposite from the controlling element 0 thesingle spark type ignition, and this per- 's the use of a straight anglearm, such 9. However, if the controlling element of the rib ating sparktype of ignition is positioned at 90 degrees from the element whi hcontrols the single spark system oi igniti n, as is shown in the switchillustrated in Fig. 2, the conformation of the arm will be is is shownin Fig. 10. The controlling elements of the ignition switch, as isclearly shown in Fig. 7, will be norinally n'niinta ned in theirinoperative position. by means oil the springs 60. The perative end ofthe mint-rolling element 54 is provided with a beveled flange l2 and theannu a1- flange 63, thus leaving a reduced portion therebetween. The armcarried by the main operating member, engages the shank of thecontrolling element 5%, directly wh n the ma pressed in, the 0.1 nflanged ire controlling at the operancnt may ent and force i p l 9 orcontact, with l above operation, "51} .4! :"i P l 11. no ioiceo. out orL'l I.

Referring to initial starting; lows: through t same arrangement as shownin the copending' application of Charles F. iietteu me, 5 ed September19, 1912, Serial No.

11,237, so far as relates to the supplemental tween the engine and thestarting device.

From the description thus far given of the )resent invention it will beseen that by what may be termed the initial operation ofthe mainoperating member, the contacts 91 and 92 will be brought together toclose the circuit for effecting the slow initial movement of thestarting device and the controlling elements of the ignition system willbe brought into such position as to establish ignition of one or moretypes. Now, it is this same operating member which, upon furthermovement, is adapted to effect the shifting of the connections betweenthe starting device and the engine, and also the shifting of theelectrical connections between the starting device and the storagebattery. However, as has been explained heretofore, it is advisable thatthe closing of the circuit to effect a slow movement of the startingdevice and the shifting of the connections between the engine and thestarting device; and the changing of the electrical connections betweenthe starting device and the battery. take place with certainpredetermined timed relation to each other. It will also be obvious thatthe circuit connections between the starting device and battery shouldnot be shifted until after the starting device has been connected up tothe engine, and it is therefore extremely advisable that the coupling ofthe engine and the starting device together, take place previous to theshifting of the batterv connections.

The arrangement for shifting the cou pling mechanism previous to thechanging of the battery connect ons, has already been fully describedand illustrated in the copending application of Charles F. Ketteringfiled June 15, 1911, Serial No. (333,443, and it will therefore not bedescribed in detail in the present case.

In order that the main operating member may be moved initiallyto'establish the circuit for effecting the slow initial movement of themotor, previous to the shifting of the coupling mechanism between theengine.

and starting device. there ispro-vided an elongated slot 105, formed inthe free end of the rod 47. wherein the pin 95 is positioned. It willtherefore be seen that this main operating member may be moved adistance equal to the extent of the slot 105, during which movement thecontact plates 91 and 92 will be brought together and the slow initialcircuit established. The pin 95, which has been described as beingpositiened in the slot 105, is carried'by the lever 100 which is sopivoted that a slight movementimparted by the main operating member toone end thereof, will effect a much great: movement of the opposite endof said lever, which end is secured to a yoke member 101, and isconnected to the coupling mechanism in a manner substantially the sameas that described in the copending application of Charles F. Kettering,filed June 15, 1911, Serial Number 6323,4 13. Now, as soon as the mainoperating member has been moved to the point where the pin 95 is engagedwith the wall, at the end of said slot, the lever 100 will be picked upand shifted by any further movement of the main operating member andthus will cause the shifting of the coupling mechanism, and theconsequent connecting up of the motor and engine. Incidental to themovement of the coupling mechanism or gearing 110, the rod 113 will ofcourse be shifted, which will also move the rod 114. This rod 114 isconnected with the movable member 26 of any suitable switch mechanism25, contained within the casing 115, and which controls the electricalconnections between the battery and electric machine.

Referring to the diagrammatic view in Fig. 1, it will be seen that thereare three operative controlling elements for the ignition switch,namely, 56, 120 and 54@, which control respectively, the vibrating sparksystem, the magneto system, and the single spark type of batteryignition. Any of these elements may be moved independently of the other,to establish a different type of ignition, independent of the movementof the main operating member, which controls the starting system, andincidentally, the ignition systems. Of course, if it is desirable, themember 49 may be constructed with three arms, so arranged that each ofsaid arms will engage with one of the controlling elements of theignition system.

Under these conditions. of course, the magncto circuit and the singlespark type of battery ignition would be brought into operative positionby the operation of the main operating member and would be maintained inposition to establish said systems by the cooperation of the springcontrolled detent. At the same time, the controlling element for thevibrating spark type of ignition would also be brought into position toestablish this system, incidental to the operation of the main operatingmember, but this latter controlling elementwould not be effected by thelatching detent and would return to its normal position, as soon as thepressure was released from the main operating memberancl said member re6 1,...7aaa1 turned by the spring 45 to its normal position.

In the co-pending application of Charles F. Kettering and llilliam A.Chrvst, tiled November 20, 1912, Serial No. 732,483, there is shown,described and claimed a releasing and locking mechanism, which isadapted to operate relative to the spring controlled detent, to releaseany of the buttons or con trolling elements of the ignition system whichare held in position to establish the various ignition circuits orsystem, and permit the same to be returned to their in operativeposition, by means of the spring member 60. In the present invention,this locking device retains certain of the functions which it had inconnection with the subject matter of the co-pending application ofCharles l Kettering and l Villiam A. Chryst, filed November 90, 1912,Serial No. 73:,183, and in addition, it has the function of preventingthe operation of the main operating member, when said locking device isin position to loclr the ignition controlling elements in theirinoperative position.

In the form shown in the drawings, the locking and releasing button 150is capable of a reciprocating movement and also of an oscillatorymovement. However, the normal position of the spring pressed plunger 151prevents the oscillatory movement thereof, except when the key element152 ms been inserted in the button 150, so as to depress the plungerelement 151, out of engagement with said button. This locking andreleasing element 150 comprises a cylindrical member 156, havingsegments at one end thereof, cut away so as to leave the projection 153,while the face of said cylindrical member, adjacent to one of thesegmental cuts is beveled as at 15 1. Norma-illy, this controllingelement 150 is so positioned that the beveled face 151 of thecylindrical member 156 lies adjacent to the edge of the springcontrolled detent, and it will be seen that upon pressing in saidreleasing element, that the detent will be engaged by said beveledportion, and gradually forced out of its normal latching position. Thus,the reciprocal movement of this locking and releasing element may bedefined as one of its releasing movements. However, when the key 152 isinserted in said element, and the same is turned, the spring controlleddetent will be engaged by the projection 153, at the end of thecylindrical member 156. Thus, the detent element will first be forcedout of its normal latching position into a releasing position, andsecondly, will be permitted to return to such a position that a portionof the detent will underlie the longitudinal axis of each of thecontrolling elements or buttons, and thus prevent further operationthereof. until this releasing button has been turned back to its normalposition, during which operation, d detent will. be forced into areleasin position. relative to any of the buttons h may have been lockedin. It will be undoi tood that the locln ellcct of this detent ble by maring the o end of the cylindrical element N that when the button is inpa T ing effect of the it c be moved over beyond its norina sitirn.
